No abnormal parenchymal signal. No hydrocephalus. No intracranial mass or haemorrhage. No area of diffusion restriction. The sella is enlarged in its vertical dimension and predominantly fluid filled. Pituitary tissue appears flattened on the floor, with the stalk in a posterior position. Optic chiasm outlines normally.
No venous sinus thrombosis identified. Both transverse sinuses are narrowed at the mid segments, with normal calibre reconstituted distal to veins of Labbe.
In this clinical setting, these findings are those of benign intracranial hypertension (pseudotumour cerebri).
